The story behind the find
Transformed 250K+ Trees in a Commercial nursery.
Dr. Mani, the founder of US Citrus Nursery developed Crab, Kelp, & Amino Acids (7-4-4).
Made from the sea (crab and kelp) volcanic ash, and nature’s source of nitrogen, amino acids —without a drop of synthetic salt.
🌿 Real Plant Nutrition. Zero Compromises.
Crab, Kelp & Amino Acids is Dr. Mani’s next-generation granular fertilizer—designed to supercharge plant growth and rebuild the soil from the roots up.
Formulated as a slow-release granular blend, it delivers complete, natural nutrition without the synthetic salts or sludge that damage your soil’s biology.
Just sprinkle it around the root zone, water it in, and let nature do the rest. And it's best used as a regimen when you apply Dr. Mani's Magic - Plant Super Boost to your plants, as well.
What’s Inside?
🦀 Crab Meal – Packed with chitin, it fuels soil microbes, supports natural plant defenses, and helps suppress disease.
🌿 Cold-Processed Kelp – Boosts root growth, flowering, and stress tolerance with powerful natural plant hormones.
🌋 Minerals from Volcanic Ash – Loaded with trace elements and silica, which strengthens plant cell walls, improves drought tolerance, and enhances structural integrity.
Natural Blood, Bone & Feather Meals with Langbeinite – A balanced source of slow-release nitrogen, phosphorus, potassium, magnesium, calcium, and sulfur. Feeds plants slowly and consistently for 4 weeks with each application.
All adding up to a powerful 7-4-4 NPK (nitrogen, phosphorus, and potassium) as well as 6% calcium and 2% magnesium, plus all the essential micronutrients!
Why It Works:
✔️ Feeds Slowly & Steadily – No nutrient dump, no risk of burning
✔️ Microbe-Safe – Doesn’t kill beneficial organisms like salt-based synthetics
✔️ Silica-Strong – Boosts stem strength, drought resistance & pest defense
✔️ No Fillers, No PFAS – Pure ingredients that build long-term soil health
✔️ Multi-Purpose – Ideal for citrus, tropicals, vegetables, lawns, flowers & trees
🍊 Especially Effective for Citrus & Tropical Trees
Born in a citrus grove and battle-tested on over 250,000 trees, this granular blend is a game-changer for tropical fruit growers.
Apply monthly for citrus, mango, guava, banana, avocado, and more. Expect deeper roots, fuller canopies, and bigger, juicier harvests.
But it’s not just for trees—use it anywhere:
Vegetable gardens, raised beds, flower beds, shrubs, turf-grass, and even houseplants.
